When paper discharge is started, the arm-type pressing member on the discharge end side of the tray moves in the pushing-up direction via the electromagnetic clutch and the torque limiter. The arm-type pressing member stops at a predetermined pushing-up position, and when the recording paper is ejected from the apparatus main body side, the driving force in the pushing-up direction disappears, and the spring force of the spring member moves it in the pushing-down direction to eject the recording paper. Hold the paper between it and the saucer.

抜き出来る。According to the present invention, the following remarkable effects are obtained. 1) The rear end side of the recording paper is sequentially stacked on a tray arranged substantially along the paper discharge direction, and at least one of the arm type pressing members and the tray are always sandwiched between the recording papers. By adopting this, a large number of recording papers can be stably and reliably stacked on the tray regardless of the size of the recording papers. 2) Since the recording paper is fixed by the spring force of the friction member and the spring member, it is securely held. Further, the spring force of the spring member can be adjusted according to the number of recording sheets to be stacked, so that the optimum holding force can be set. 3) It suffices if there is a space in which the arm-type pressing member can rotate, so that the space of the recording paper tray can be saved. 4) The rotation of the arm type pressing member is performed through the electromagnetic crack and the one-way torque limiter, and the idling torque value of the torque limiter is set to be smaller than the transmittable torque of the electromagnetic crack and larger than the axial torque of the spring member. There is. Therefore, even if the arm-type pressing member stops at a predetermined position while the electromagnetic crack side is driven, and even if the number of recording sheets stacked on the tray changes, the stopped state can be maintained without any problem. I can. 5) The stacked recording papers can be easily pulled out against the spring force of the spring member, which is set to an appropriate strength.
